Agree with most points.
At the end off the day, copying or not - no one can do anything about it and that's what makes it doubly frustrating but being angry or annoyed doesn't help either.
Learn to deal with it - I have.
In a negatively positive way (if that makes sense) people producing similar stuff motivates me to go and make something twice as better - might just be my competitive streak talking though. :P
I'm not gonna say anything patronising like 'take it as a compliment' because that line annoys the heck out off me too but.. If you love sig making you'll still make ur stuff no matter what... it's a hobby afterall. The only valid reason to give up any hobby is if u honestly stink at it..
Actually even then you shouldn't give up... :P
Jokes apart... thanks for the post Vasu n Mels!!!
